JPH08283622A - Releasable resin composition against polluting material and fungicide - Google Patents

Abstract

PURPOSE: To prepare a releasable resin composition against polluting materials capable of being easily peeled off together with the polluting materials by washing by dissolving a specific resin in an aliphatic lower alcohol, sealing an oxidizing bleaching agent in polluted parts, improving washing effects and preventing volatilization of the bleaching agent into air. CONSTITUTION: This releasable resin composition against polluting materials is prepared by dissolving preferably 3-10 pts.wt. of (A) a resin having peelable film forming ability (e.g.; PVA, modified polyurethane, etc.) in 100 pts.wt. of (B) an aliphatic lower alcohol (preferably an alcohol safety to human bodies such as ethanol, isopropyl alcohol, etc.) or a mixture solvent of the alcohol with water. It is preferable to add a chlorine-based or an oxygen-based oxidizing bleaching agent to the objective composition. As the chlorine-based bleaching agent, e.g. sodium hypochlorite can be cited. As the oxygen-based one, e.g. sodium percarbonate can be cited.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a resin composition for removing contaminants and a fungicide.

[0002]

2. Description of the Related Art Bathroom walls, ceilings, joints, etc., walls of living spaces with poor air permeability, ceilings or walls that have been covered with bookcases, indoor greenhouses, etc. for a long period of time are dusty or damp. Molds and bacteria propagate using filth as a nutrient and leave colored stains due to metabolites, which can be controlled hygienically and aesthetically.

Conventionally, a cleaning agent using sodium hypochlorite is applied to the contaminated portion or sprayed, or the cleaning agent is soaked in a thin tissue paper or the like and attached to the contaminated portion. I sterilized and bleached.

When pollutants cannot be removed by the above method, water is applied to the contaminated portion, for example, a joint portion such as a bathroom wall, and a cleanser containing a bleaching agent such as sodium hypochlorite is sprinkled. A rough method of scrubbing with a sponge brush and washing with water was adopted.

The magazine SOAP / COSMETICS /
CHEMICAL SPECIAL TIES (1994
As a recent information, the February issue, pages 50 to 54) discloses a gel type cleaner having an abrasion resistance and a bleaching function, and an aerosol type cleaning agent for bathroom tiles.

However, it is troublesome to use any of the above-mentioned cleaning agents, and in addition, the sodium hypochlorite irritating odor does not disappear even after a considerable time has passed since the cleaning operation was started.
The cleaning agent drips and disperses and the cleaning effect is not sufficient.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above facts, and its object is to seal a chlorine-based or oxygen-based oxidative bleaching agent used in a contaminated part. The resin composition for removing contaminants and the fungicide for enhancing the cleaning effect, preventing the volatilization into the air in the vicinity, and being able to use comfortably, and easily removing the contaminants together with the contaminants after cleaning. To provide.

[0008]

The present invention according to claim 1 is characterized in that a resin capable of forming a peelable film is dissolved in an aliphatic lower alcohol or a mixed solution of an aliphatic lower alcohol and water. A resin composition for removing contaminants,

The present invention according to claim 2 is characterized in that a chlorine-based or oxygen-based oxidative bleaching agent is added to the contaminant-peeling resin composition according to claim 1. Composition,

The present invention as set forth in claim 3 is a gist of the fungicide, which comprises the resin composition for removing contaminants according to claim 2.

As the aliphatic lower alcohol, an aliphatic alcohol having a carbon number of 4 or less is used, and ethanol, isopropyl alcohol, etc., which are safe for the human body, are preferably used.
In the present invention, the aliphatic lower alcohol used as a solvent for the resin having a peelable film forming ability may be used alone or in combination of two or more kinds. or,
A mixed solvent of the above aliphatic lower alcohol and water may be used.

The resin capable of forming a peelable film is, for example, polyvinyl alcohol, carboxymethyl cellulose, methyl cellulose, polyvinyl pyrrolidone, polyvinyl butyral, modified polyurethane, modified vinyl acetate, acrylic acid-soluble in the above aliphatic alcohol. Examples thereof include, but are not limited to, a methacrylic acid ester copolymer. These resins may be used alone or in combination of two or more kinds.

The resin capable of forming a peelable film is 1 to 30 parts by weight, more preferably 3 to 10 parts by weight, based on 100 parts by weight of the aliphatic lower alcohol or a mixed solvent of the aliphatic lower alcohol and water. It is desirable to be blended in parts.

The chlorine-based oxidative bleaching agent is not particularly limited as long as it has an oxidative bleaching performance, and examples thereof include sodium hypochlorite, bleaching powder, advanced bleaching powder, and sodium chlorite. Examples include dichlorinated isocyanuric acid and the like. Further, the oxygen-based oxidative bleaching agent is not particularly limited as long as it has the oxidative bleaching performance as in the above, and examples thereof include sodium percarbonate, sodium perborate, potassium persulfate and the like. To be

The chlorine-based oxidative bleaching agent has a stronger bleaching action than the oxygen-based oxidative bleaching agent and is suitable for removing contaminants in the joints of the bathroom. If the method is erroneous, the wall material or carpet made of vinyl chloride resin may be discolored, so it is preferable to use it properly for each application.

In the resin composition for removing contaminants and the fungicide of the present invention, the resin having the peelable film-forming ability is dissolved in the aliphatic lower alcohol or a mixed solvent of the aliphatic lower alcohol and water. A chlorine-based or oxygen-based oxidative bleaching agent is mixed, but if necessary, an antioxidant or a UV absorber may be blended, or an antibacterial agent may be blended. In particular, if the bathroom cleaner contains an antibacterial agent, the cleaning effect can be maintained for a long time.

[0017]

The resin composition for removing contaminants and the fungicide of the present invention include a chlorine-based or oxygen-based oxidative bleaching agent as an aliphatic lower alcohol or an aliphatic lower alcohol of a resin having a peelable film-forming ability. Since it is contained in a water solution, the chlorine-based or oxygen-based oxidative bleach used is sealed in the contaminated part to enhance the cleaning effect and prevent it from evaporating into the air nearby. It is comfortable to use and can be easily removed from the contaminated area with contaminants after cleaning.

EFFECTS OF THE INVENTION Since the resin composition for removing contaminants and the fungicide of the present invention are constructed as described above, the coating film can be formed even on joints and other uneven surfaces of bathrooms that are difficult to clean. A coating film can be formed on these contaminated surfaces without dripping and with good workability, and is firmly adhered to the coated surface without peeling or rising during use. Since the chlorine-based or oxygen-based oxidative bleaching agent is sealed in the coating film formed on the contaminated surface, the unpleasant odor of the chlorine-based or oxygen-based oxidative bleaching agent fills the surrounding area after application. Without doing, and
Can be bleached and cleaned effectively. It can be easily peeled off from the coated surface after use and does not damage the coated surface such as the bathroom wall.
